Abstract

Microwave (MW) is applied to enhance chlorobenzene (CB) removal using micron iron (μ-Fe) particles, nanoscale iron particles freshly prepared in our lab (nP-Fe0), and commercial nanoscale iron particles (nC-Fe 0) as the dielectric media. The results show that when the CB solution is irradiated with 250 W MW for 150 sec, better CB removal can be achieved than without MW irradiation. The MW radiation increases the iron oxidization rate, surface activity, and hence the CB removal rate. The MW-induced iron particles are capable of removing 13.6 times (61.2% vs. 4.5% for μ-Fe), 2.8 times (76.5% vs. 27.5% for nP-Fe0) and 3.6 times (65.4% vs. 18.1% for nC-Fe0) more CB, and the CB activation energy is decreased 16.8 kJ/mol (μ-Fe), 3.2 kJ/mol (nP -Fe0) and 3.5 kJ/mol (nC-Fe0). Using the microwave induced Nano-scale Iron Fluidized is effective in decomposing toxic organic substances as demonstrated in this laboratory study.
